5pb. may have a Steins;Gate sized hit on its hands with Robotics;Notes. CEO Shikura Chiyomaru revealed at Twitter today that orders for the game (presumably orders from retailers to secure copies of the game) crossed the 80,000 mark as of last week. The PS3 and Xbox 360 multiplatform title sees release on the 28th.
Chiyomaru did not provide similar data for other games in the same "science adventure" series, which also includes Chaos;Head and Steins;Gate. However, he did note that the success of Robotics;Notes represents a tremendous advancement when compared to the initial release of Steins;Gate. He added that it's the ultimate feeling to see the adventure game field heat up with the new game.
